Although interdiff may save you a step or two you are generally advised to
do the additional steps since interdiff can get things wrong in some cases.

===============

release is the most recent.
If regressions or other serious flaws are found, then a -stable fix patch
-will be released (see below) on top of this base. Once a new 4.x base

-To apply a patch moving from 4.6 to 4.7, you'd do the following (note
-that such patches do **NOT** apply on top of 4.x.y kernels but on top of the
-base 4.x kernel -- if you need to move from 4.x.y to 4.x+1 you need to
-first revert the 4.x.y patch).

-The 4.x.y kernels

=================
Kernels with 3-digit versions are -stable kernels. They contain small(ish)
critical fixes for security problems or significant regressions discovered
-in a given 4.x kernel.
+in a given 5.x kernel.
This is the recommended branch for users who want the most recent stable
kernel and are not interested in helping test development/experimental
versions.

.. note::
The -stable team usually do make incremental patches available as well
as patches against the latest mainline release, but I only cover the
non-incremental ones below. The incremental ones can be found at

-These patches are not incremental, meaning that for example the 4.7.3
-patch does not apply on top of the 4.7.2 kernel source, but rather on top
-of the base 4.7 kernel source.

-So, in order to apply the 4.7.3 patch to your existing 4.7.2 kernel

-base 4.7 kernel source) and then apply the new 4.7.3 patch.

stuff (such people should see the sections about -next and -mm kernels below).

suffix denotes the version of the kernel that this -rc kernel will eventually
turn into.
-So, 4.8-rc5 means that this is the fifth release candidate for the 4.8
